Artificial neural networks (ANNs) have been applied to a variety of classification and learning tasks. The use of evolutionary algorithms (EA) as one of the fastest, robust and efficient global search techniques has allowed different properties of artificial neural networks to be evolved. This paper proposes the possibility of using differential evolution for determining an ANN architecture (DNNA)...
High-tech industry zone play a important role in the global economic system with the continuously new knowledge innovation, itpsilas becoming the main motion of regional economic structure optimization and competition. The technology ability and diffuse effect of High-tech zone influence itself and regional economic development greatly. This paper design High-tech zone technology innovation ability...
Elevator group control system (EGCS) with multi-objective, stochastic and nonlinear characteristics is a complex optimization system. After analyzing characteristic of typical traffic mode of elevator. This paper proposed a new simulation platform of an elevator group control system implemented in C# using the fuzzy-neural network technology. The result of simulation shows that this method realizes...
This paper presents a modified multi-colony ant algorithm, based upon a pheromone arithmetic crossover and a repulsive operator. Iteration of this algorithm can avoid some stagnating states of basic ant colony optimization. An important mechanism of this algorithm is the reinitialization of such stagnating states (worst performing ant colonies), which is accomplished through application of the pheromone...
In order to solve assets allocation problem with fuzzy uncertainty, a fuzzy portfolio selection model is used in this paper. By introducing a coherent risk measure named fuzzy conditional value-at-risk in possibility spaces, the model can rationally solve fuzzy assets allocation problem. Impractical results indicate that efficient frontier of the model is a band. This approach can effectively solve...
In this paper, a target tracking problem for the portfolio selection involving options is studied. In particular, the portfolio in question contains a stock index and some European style options on the index. And the tracking models with fixed or random target values are investigated, respectively. The tracking-error-variance (TEV) methodology is adopted in our approach to formulate the problems,...
We develop a dynamic realistically model of a typical Chinese resident with stochastic labor income, risky owner-occupied house, housing rental market and costly adjustment in housing of Chinese real estate market, and try to analyze the optimal life-cycle portfolio choice for Chinese residents with housing factors. Our analysis indicates that home ownership crowds out stock investment of Chinese...
In this paper we introduce a framework for constructing portfolios, addressing two of the major problems of classical mean-variance optimization in practice: Low diversification and sensitivity to information ambiguity. In order to address these issues, we incorporate a prior regarding investors preferences as well as using a bootstrapping method to incorporate the effects of input parameter variation...
The ERP II implementing options are enlargement of the financial options. Its essence is object item investment and policy decision of management. In this paper ERP II implementing option functions of client and vendor are described. The optimization investment policy decision of the ERP II implementing option has been analyzed under different information conditions. The vendor of ERP II implementing...
In order to analyze the impact of consumer's life-level on R/M integrated supply chain management, a method to describe the effect of the consumerpsilas life-level on the collecting price is shown, then an optimization model of R/M integrated supply chain by applying the description method is improved, and finally, the impact of consumerpsilas life-level on the management of R/M integrated supply...
This article presents a robust optimization formulation for dealing with raw materials price uncertainty in an oligopolistic competition market scenario. Participants in the market face equilibrium selling price and uncertain production cost, at the same time. We show that the robust optimization formulation, based on a nominal problem, may be articulated as a variational inequality involving control...
Hypothetical queries evaluate the effect of adopting or changing some strategy then aiding in decision making. Hypothetical queries simulate some modifications and assess the effect. But in OLAP environments modify data will result in cube recomputation which cost heavily. Through observing and analyzing, hypothetical queries are described as follows: first, dicing the needing hypothetical modified...
This paper derives the optimal consumption and portfolio choice pattern over the life-cycle for households facing uninsurable labor income risk, ruin risk, stochastic capital markets, and uncertain lifetime. Our model posits a dynamic utility maximized with CRRA and Epstein-Zin preferences that has access to liquid stocks, bonds, and illiquid life annuities. The empirical results of this research...
On the basis of the analysis on the theories and methods on relative entropy and with the union of extension transformation and entropy optimization, this paper establishes the reliability and sensitivity analysis model of extension group decision-making centered on optimizing decision-making. With the implementation of the reliability analysis of extension group decision-making and the categories...
E-business and strategic management problems in digital information management (DIM) methodologies can be efficiently solved by using corresponding adaptive algorithmic procedures. A case study representing a characteristic e-banking sector problem and strategic management methodologies in DIM related to e-banking management is presented by considering the proposed algorithmic approach. The adaptability...
The growing number of crisis situations around the world in recent years has highlighted the urgent need to improve the capability of emergency response systems. When an emergency happens, the most important response is to promptly evacuate victims or potential victims from dangerous areas to safe places. The use of decision support systems can not only improve the efficiency of evacuation but also...
With the development of e-technology and Internet, information technology is introduced to commercial activities as a tool, which creates a new business operation e-commerce. Meanwhile, Chinese entrepreneurs have gradually realized that there is no doubt that competition among the enterprises is becoming the competition among their supply chains under the economic globalization in 21st century. The...
